Production introduction

The guide wheel is used to guide the track to rotate correctly to prevent its deviation and derailment.            

Most excavators also act as supporting wheels. This can increase the contact area between the track and the ground and reduce the grounding pressure. 

The wheel surface of the guide wheel is made into a smooth surface, and the middle arm ring acts as the guide, while the torus on both sides supports the rail chain.            

The smaller the distance between the guide wheel and the nearest supporting wheel, the better the guidance.

We control all procedure very strictly. We guarantee one year for our brand idlers.

Our idlers are applicable for Komatsu, Hitachi, Kobelco, Daewoo, Hyundai, Volvo, Jcb etc. We can also offer OEM service according to your drawings or samples.

Advantages

Brackets

Brackets of idler roller are made by ductile iron. It shows exceptional resisitance to shock.

Bimetal bushing

Bimetal bushing of our front idler is based on steel plate which special alloy is sintered on it. It shows high loading ability and high ability of fatigue resistance.

Cost saving service life

The heavy profiles of idler roller rims are carefully heat treated in depth for extra service life.

Floating seal group

Floating seal group of our of idler group has super seal performance under bad working conditions like being muddy or steamy etc.. it is applicable for the condition of low speed and heavy load. And it is anti-friction and can be auto-compensated after wearing.

Lubrication oil

Lubrication oil of our idler assy is selected carefully. It can lubricate shaft and bushing well to lower the wearing utmostly. And it can cool the roller perfectly. Those maximize the inner structure life.

Attentions while assembling the rollers

1. Before assembling rollers,smooth the sharp part of sapre parts and do the deburring,clean the inner holes of the roller body and oil seal etc..

2. Do not break and scratch any part of the sealing parts.

3. Do not oil and distort the rubber floating seal ring during assembling the rollers.

4. A small amount of oil should be covered on the contacting surface while fitting the floating seal group.

5. After finishing the assembling process,fill clean extreme-pressure vehicle gear oil to take 80 percent of the inner cavity of roller body and do the running test then confirm no leakage after 4 hours.
